I gave headphones a worthy effort, but they drove me nuts. On warms days they made me sweat. When on my knees digging and looking down at the hole they continually tried to slide forward. My fix was to use ‘sport earbuds’ that hook behind the ear. They stay in place. I routed their wire to a volume control banded to the Hori knife sheath on my belt, and from there to the detector via a 10’ [stretched] coil cord. It all works like a charm with freedom of movement, no binding or pulling, no sweat, and it wasn’t very spendy.
